New Conformity Model Proposes Disregarding Outlier Opinions
Researchers have introduced a redefined conformity model that suggests individuals may disregard outlier opinions when forming a consensus. This approach contrasts with the widely recognized French-Harary-DeGroot model, which typically assumes all recommendations are carefully weighed and averaged. The new model, developed by SFI Complexity Postdoctoral Fellow Kaleda Denton and colleagues, offers a different perspective on how collective opinions might be formed by selectively focusing on common viewpoints.

A redefined model of conformity explores how individuals process varying opinions within a group. This new model suggests that when faced with a range of recommendations, individuals might disregard outlying views in favor of more common responses.
This stands in contrast to the French-Harary-DeGroot model, often referred to as the DeGroot model, which is a popular framework for understanding conformity. The DeGroot model posits that individuals would carefully weigh all inputs, calculating an average to reach a consensus.
To illustrate the difference, consider a scenario where five people suggest 15 minutes per pound to roast a turkey, while one person recommends 33 minutes. Under the traditional DeGroot model, the collective decision would be an average of all inputs, resulting in an 18-minute per pound recommendation.
However, according to the model previously published by Kaleda Denton and her colleagues, the outlier recommendation of 33 minutes would be disregarded. The group would then likely proceed with the more common 15-minute recommendation.
According to Phys.org, this new model presents an alternative view on opinion dynamics and collective decision-making processes.
